DUMP-CAR CONSTRUtJTION 6R THE LIKE.

' Be it known that I, JOHXPEARSQS, a'citizen of the United States, residing at Chicago, in the county of -Cook and State of Illinois, have invented certain'new and use ful- Improvements'in -Dum -Car Construc tions or the Like, of which t e following 15 a,

description;

My invention'belongs to. that class of de vices known as car constructions or the like,

and relates particularly'to certain dump.

doormech'anism and to the construction of. the car, having among its objects the production of a simple, convenient, durable, efs ficient and Satisfactory construction of the kind described for use wherever found ap plicable.

To thisend my invention consists in the novel construction, arrangement and combination of parts, herein shown and described and more particularly pointed, out in the claims.

.Referrii tothe drawings in which like reference 'c aracters indicate like or corre spondmg parts, Figure 1- 1s a cross sectional view of a portion of a car showing one of the dump doors open, Fig. 2 1s a similar cross sectional View showing the door closed, Fig.

3 is a to plan view of the bottom of a portion of the car showing the door closed and also a portion of one door opening, the door removed,Fig. 4 is a side elevation of a portion ofthe car, Fig. 5 is a sectional view taken substantially on line of Fig. 2, Fig. 6

is a perspective 'iew of-one of the winding shaftsupports and door hinge, Fig.7 IS a View of one of the winding shaft drums,

Fig. 8 is a sectional view of a modified form of side beam taken substantially on line 88" of Fig. 9, Fig. 9 is a top elevation of a portion of the same, Fig. 10 is an end elevation of a portion of the car showing suitable mechanism for operating one of the winding shafts.

The complete car is not shown in all its details inasmuch as the body of the car may be constructed in any suitable manner. As

shown,- it comprises beams 1 arranged centrally and longitudinally of the car, sidewalls 2 and end walls 3. 'The car is -,pro-

.vided with a plurality of dl'mip'doors'. 4

preferably arranged and hinged centrallylongitudinally of the car to form the bottom each (1001'.-

or floor when-closed. As shown, the doors 'are-preferablv DiVotallV securecl'to a plural ity of brackets 5, etc. carried by the beams 1,

the'constrriction of the brackets being more car are orovided withposts and are inwardly'o set, as at 8;- i

'At the sidesof the car-1 arrange a 2 bar 9*10 extending along the side of the car and provided at intervals with a plurality of transverse openings 11 therethrough.

fully explained hereafter. The sides of the 3 Suitably pivotally carried from the beams '910 are a. plurality of hook members-12 which support and lock thedoors in their closed positions. The book members 12 are each pivotally supported as at 13 see Figs.- 1, 2

and 5, by means of suitable brackets 14 or their equivalents secured to the beam 91O and the part8 of the side walls. There may be'any number of hooks and brackets 1-1 therefor; as shownytwo' are provided for Figs. 8 and '9 instead offoneintegral Zbar I show two angle bars 37 and 38 provided with openings: 39 cuttherethrough from one angle to the. edge, which bars may be se-' cured'together in any suitable way. This construction is the equivalent of the 2 bar 9-101 above mentioned, but owing to the double thickness issomewhat stitl'er and stronger. By the use of the 2 bars or their equivalents not only do the beams have great 8 stilfn'css or rigidity, but the hooks are fully protected. It'will be noted that the books 4 are covered and protected by the brackets '14 and these with the Z beams protect the In the construction shown in books from the weather as well as. from inpie es of shaft on each side of the car,.each

one cbntrolling one half of the doors on that ;side,'. being preferably provided. On the winding shaft :15, which may be'anade square, hexagonal ;-o rthe like, are arranged drums. 16, fto which-are secured the cables no 17 the opposite end of the cables being se-- cured to the forked ends 18 of the books 12 by means of pins 19 or their equivalents."

' Each of the drums is provided with an extended part or hearing 20 preferably flanged as at The-brackets before mentioned, .are made 1h the formsof hooks, as at 22,

and each arrangedto support the extensions a 20 or bearings onthedrums and the winding shafts passing thcrethrough, the flanges 2L preventing movement of the drums longitudinally the winding shafts and the irregular shape of the shafts preventing rotation of thedrums thereon.- The hook part is preferably extended back slightly as at'23 to prevent the winding shaft and drums from raising during the operation, it beingnecessary to push theshaft toward the beam'l as well as to raise itwhen removing. Y

The edgesof the doors are preferably provided with rolls 2- one for each chain 1'7, and with a Z bar or beam 25 havin openings 26 therethrougb, throu h which the flexible members'may ass.- Ihis construetion guides and keeps t 1e flexible member 17 in placeon'the. rolls 24. The Z bars may therefor. Any equiva ent devices may be by means of a oeking awl 32 and a lock 33 employed.

The hooks or members 12 may be locked in operative position when the doorsare closed in any suitable or preferable manner.

As shown,-this is accomplished by means of I lookin rods34 carrying members 35 arranged ta force V the locking members or hooks into operative position'when the doors are closed. The rods 34 may be operated by means ofsu-ita'ble levers '36 or their equivalents. In the preferred construction I use two locking bars 'on each side of the car, one

' controlled from each end of the car for each half of the hooks on that side. 0

It should be particularly noted that m the construction of car shown and described the lockingfmembers or hooks are fully pro-i 'tected, the chains or flexible members are maintained inposit-ion-relatlve to the free edges of the doors, and the drums are secured on the winding shafts so as to rotatably support the same, and yet so that they will not rotate about or move longitudinally of the shafts. WVhen the drums are so maintained in position it is unnecessary to'secure them to the \vinding'shafts with screws,

c said openings, and

bolts. or the like and thereby possibly weakening the same'or the winding shaft, thereby giving a more substantial andrigid OOH? struction.

Having thus described my invention it is obvious that various immaterial modifiea tions may be made in the same without de-f parting from the spirit, of "my invention,

hence l do not wish to be understood as lim iting myself to the exact-form oonstruction, arrangement or combination of parts herein shown or described or uses mentioned.
